When I go to my Drupal 6 professional blog, <a href="http://awebfactory.com.ar" title="http://awebfactory.com.ar">http://awebfactory.com.ar</a> , I
get a popup (whether logged in or not) that says:
"Authentication required" A username and password are being requested by
<a href="http://dc2009.drupalcon.org" title="http://dc2009.drupalcon.org">http://dc2009.drupalcon.org</a>. The site says: "drupalcon security lockdown"
When I hit cancel, everything is OK, until I access another page and the
same thing happens.
It's Drupal 6, and I have just upgraded Drupal and all modules to latest
release with no exceptions. I deleted the .htaccess and replaced it with a
new one from the Drupal 6 release.
